SPORIAN MICROSYSTEMS, INC — National Aeronautics and Space Administration SBIR Phase I: A1

Description

The U.S. hypersonic ground- and flight-test communities require advanced Instrumentation systems that can inform a vehicle structural health monitoring (SHM) system operating in extreme hypersonic environments, with the long-term goal of deployment on an operational hypersonic aircraft allowing maintenance requirements and life predictions to be based on the vehiclersquo;s/systemrsquo;s actual flight history and improved vehicle/system reliability.nbsp; A specific extreme environment instrumentation need, with application to both airframe and propulsion systems, is inertial vibration measurements at high temperatures and high acoustic levels. An ideal such sensor would not only operate at extreme temperatures, but also be very small/lightweight, easy to integrate, and include intelligent sensor functions such as internal data processing, temperature compensation, output in engineering units, internal health test, and supporting digital bus communications.Sporian Microsystems has significant prior experience in the development of ultra-high-temperature sensors for aerospace propulsion and ground power energy generation applications. The long-term objective of the proposed effort is to heavily leverage this prior work and translate it to realize an ultra-high temperature (gt;1000deg;C/1830deg;F) inertial vibration sensor that can be integrated with hypersonic vehicle structures and ground test/flight systems for SHM.Phase I effort will include: 1) working with NASA and industry stakeholders to define system requirements am foster transition; 2) evaluating revised hardware/electronics architectures and designs; and 3) proof of principle testing and demonstration using benchtop-scale prototype hardware. If successful, Sporian will be well positioned for the Phase II efforts focused on full system prototyping and relevant environment testing/demonstration to satisfy NASArsquo;s technical readiness level expectations.
